Abstract

In a method and apparatus for providing system interoperability in wireless communications an IP based client-server application maintains a proper set of PDP contexts while a mobile is connected via an IP based system. The application client resides in the mobile and the server resides within the network at a common anchor point between the IP based system and a PDP context based system. The PDP contexts are kept up to date but on hold until a handover occurs for the mobile from the IP based system to the PDP contexts based system.

INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates generally to wireless communications, and more particularly to system interworking in wireless communications. [Prior Art], Guang's deployment of wireless communication systems to provide various types of communication content, such as #声,资料, etc. These systems can be used to support communication with multiple users by sharing available system resources (e.g., bandwidth and transmission power). Examples of such multi-directional access systems include a code division multiple access (CDMA) system, a time division multiple access (TDMA) system, a frequency division multiple access (FDMA) system, a 3GPP long term evolution (1/^) system, And orthogonal frequency division multiple access (OFDMA) systems. Generally, a wireless multiple access communication system can simultaneously support communication of multiple wireless terminals.

For purposes of clarity, the following describes some aspects of the technology for a 3GPP SAE system and a GPRS system. And the SAE and GPRS terminology is used in the following extensive description. The term PDP context is used as an example of a specific bearer through the system. This concept also covers other bearer-based systems rather than PDP context-based systems, such as peer-to-peer based communication. Protocol (PPP) connection, bearer or any other layer 2 or layer 3 bearer system. The term GPRS type system is applicable to any system with bearer based transmission on the access interface. 125365.doc 200833141 Term User Equipment (UE) , mobile device, mobile device and the like refer to an end user device for accessing at least one of the mentioned systems. Access may be over a radio, wireless or wired interface. In an embodiment, the problem to be solved In order to enable fast intermediate system conversion between a PDP-based system and an IP-based system, it takes a lot of time to set the PDP context after switching to a PDP-based system without specific configuration. Any smoothness in inter-system change. The reason is when the mobile device is connected via an IP-based system or PDP information or Any other bearer information is not maintained as current. The specific configuration mentioned here will be described below. The following description uses an IP-based 3GPP SAE as an example of an IP-based system, but it will also apply to Evolutionary 3GPP2 system, WiMax, high speed OFDM, IEEE system or any other system without PDP context. The system used as an example of a PDP context based system is a 3GPP GPRS system, but the description is also applicable to any other bearer based transmission. In an embodiment, an aspect is such that the PDP context is maintained when connected via an IP based system. The PDP context is established and can be provided through a transparent tunnel through the IP-based system such that PDP context information is available to both the mobile device and a core network node in a system, thereby providing a PDP context based system ( Smooth switching such as GPRS).

The application client 105 resides at the mobile device 101 and the application server 107 resides in a universal anchor point 109 between an IP-based system and a PDP context-based system 111 (such as GPRS) within the network. At the office. The application monitors the services used by a group of mobile devices via an IP-based system and establishes a PDP context to be requested to carry the same set of services over a GPRS system. These PDP contexts are maintained as current at both the mobile device and the network server, but otherwise maintained as a hold. When a handover to GPRS is required, the PDP context moves to the PDP context termination point: the mobile protocol stack, the ''standby SGSN1' function 113 at the IP-based system and the GGSN (gateway) also in the IP-based system.

The SGSN in the network communicates with the "standby SGSN" communication at the IP-based system using GTP on a standard Gp interface (as depicted by GTP/Gn in Figure 1). Regardless of what services are used by the IP-based system for mobile devices, (retained) PDP contexts that support a similar service group are maintained at the UE and on the management network side. When changing through a service group of an IP-based system, the necessary modifications to the (maintained) PDP context group can be performed (if any is 125365.doc -10- 200833141). The ip-based system itself is unaware of the PDP context maintained at the end of the tunnel and at the end node of the tunnel in the network. Each of the elements shown in Figure 1 will be described in more detail below. GGSN Termination: This is a function within an IP-based system in which the connection via the GPRS system is terminated. From a GPRS perspective, &quot;GGSN terminates, as one of the GPRS systems rules GGSN action. Standby SGSN: This is a function within an IP-based system that emulates the SGSN functionality of an IP-based system. From a GPRS perspective, ''standby SGSN,' acts as one of the GPRS systems rules SGSN. PDP Compatibility Application: This is an IP-based application for managing PDP contexts when mobile devices are connected via an IP-based system. The application contains the signal transmission between the ''PDP Compatibility Application Client'' (PCAC) at the UE and the &quot;PDP Compatibility Application Server&quot; (PCAS) at the IP-based system. A set of appropriate PDP contexts are maintained between the UE and the system to facilitate a possible intersystem conversion. When the UE stays connected via an IP-based system, the PDP context information is just maintained to be up-to-date, otherwise it will remain maintained for a potential inter-system change. The communication between PCAS and PCAC is performed by the exchange of GPRS SM and MM type messages on an IP tunnel between the client and the server. The IP tunnel is carried on an IP-based SAE system. PDP Compatible Application Server (PCAS): This is a server for managing PDP context information on the network side of an IP-based system. The PC AS communicates with the PCAC at the UE over an IP-based tunnel. PCAS also communicates with IP-based 125365.doc 11 200833141 system network functions ''standby SGSN' and &quot;GGSN termination&quot; to maintain the synchronization of these three entities. PDP Compatibility Application Client (PCAC): This is The UE that maintains the PDP context information on the UE side when the UE connects through the IP-based system. When the UE stays connected through the IP-based system, the PDP context information - just stays up-to-date, otherwise it will be a potential Inter-system change maintenance. To maintain. PD information moves from the end point of the system to the real PDP context termination point at the UE. _ From IP-based system to GPRS conversion from IP-based system to PDP-based system At the start of the conversion/switching, the maintained PDP context information from the ''PDP Compatibility Application Client') is then copied to the real PDP context termination point to be initiated at the mobile device (UE). Similarly, the PDP context information from the "PDP Compatibility Application Server" is copied to the real PDP context termination point in the network (GGSN) to be activated. Similarly, the PDP context information can be similar. Available in the SGSN (&quot; 10 Standby SGSN&quot;) from the perspective of a PDP-based system (eg, GPRS). During handover, if necessary, due to the switching between a PDP-based system Real Source Communication, PDP-based system target SGSN and &quot;standby source SGSN&quot; communication. IP-based system &quot;GGSN termination&quot; operates as the GGSN of the target GPRS system. Switching from GPRS to IP-based systems When a mobile device is connected via a GPRS system, the connection is still terminated via the &quot;GGSN termination&quot; at the IP-based system. Based on the PDP context established for the user through the 125365.doc -12-200833141 GPRS system, the IP-based system can pre-establish/establish capabilities within the IP-based system to transport a similar service group through the IP-based system. This may include the allocation or preparation of appropriate IP QoS policies to appropriate nodes within an IP based system. If necessary, a tunnel through the GPRS connection can be established to prepare/establish the necessary IP-based context at the UE. Procedure when the UE is in GPRS • The UE and GPRS specific part of the system shall operate as specified for the GPRS system, except as discussed in the literature. _ When the UE is in the IP-based SAE procedure When the UE is connected to the system via the IP-based SAE, no PDP context information is required for the purpose of SAE transmission. However, PDP context information must be maintained as up-to-date with switching from one-to-one PDP context-based systems such as GPRS. In order to keep the PDP context up to date, the content between the PCAC and PCAS exchange UE and the SGSN is similar to the application level signal transmission specified for GPRS to maintain the PDP context information up to date. The information to be exchanged can be derived from the TS 23.060 by replacing the UE with PCAC and by a basic GPRS transmission over an IP tunnel based on the IP-based system. The PDP state is stored in the PCAC at the UE and in the PCAS of the IP based system, and is put into use when the switching or conversion of the GPRS is to begin. The PDP context information at the PCAS and PCAC shall remain in this state for a long time, wherein the presence of a similar type of PDP context on GPRS will be able to carry the set of IP flows on the GPRS system in the event of a possible event of handover between systems. . Inter-system procedures 125365.doc -13- 200833141 The procedure between an IP-based system and a system-based GPRS is similar to the GPRS patent specification, such as those described in 3GPP TS 23.060. With regard to the conversion from IP-based systems to GPRS systems, the procedures in TS 23.060 should be interpreted as follows: • “Old SGSN” is represented by the “standby SGSN” function of the IP-based system (within SAE positioning) • GGSN is based on IP The ''GGSN Termination Function' of the system is indicated (within SAE Positioning). • The procedures within the source GPRS system are replaced by appropriate procedures within the IP-based system. About the conversion from GPRS-based systems to IP-based systems, TS The procedure in 23.060 should be interpreted as follows: • "New 8081^" is represented by the "standby SGSN" function (within SAE positioning) by the IP-based system. • The GGSN is represented by the ''GGSN Termination'' function (within SAE positioning) of the IP-based system. • Programs within the target GPRS system are replaced by appropriate procedures within the IP-based system.
